Application filed February 16, 1903. Serial No. 148,583. (No model.)

To all whom/ it may concern:

Be it known that we, JOHN OOONNOR and COLLATINUS A. TURNER, citizens of the United States, and residents of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Alarm for Water-Containing Vessels, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for giving an alarm when the water in a boiler or other vessel rises or falls beyond desired levels and also to control the inlet of water when the same becomes low, an object being to provide a device for this purpose that shall be simple and compact in construction and pbsitive in its action.

We will describe an alarm for water-containing vessels embodying our invention and then point out the novel features in the ap pended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is an elevation, partly in section, of an alarm for water-containing vessels embodying our invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1, and Fig. 4. is a detail View of the joint between a two-part lever employed.

Referring to the drawings, 5 designates the water-cylinder, designed to have a pipe connection 6 at its upper end with the upper portion of a boiler or other water-receptacle, and its lower portionhas a pipe connection 7 with said boiler or the like. The cylinder is provided with a water-gage 8 and also with outlet-valves 9 1O 11. Extended outward from the cylinder and having communication therewith is a casing 12, through which the stem portion 13 of afloat 14 passes. The float 14 is arranged in the cylinder and designed to be operated by the rising and falling The stem 13 of the float is con nected to a shaft 15, extended transversely through the outer end of the casing 12, and an outwardly-extended portion of this shaft has connection with a pointer 16, the free end of which is arranged to move over a guideplate 17, which will have marks on it to indicate the depths of water that may be in the cylinder. The alarm device, here shown as a bell 18, has connection with a binding-post19 on a plate 20 through a wire 21, and it also has connection with the pointer 16 through a wire 22, in which a battery 23 is arranged. A shuntwire 2st connects a binding-post 25 on the plate 20 with the wire 21, and from a binding-post 26 on said plate a wire 27 extends to a solenoid 2S,while a wire 29, leading from said solenoid, connects with the wire 22. Thus the circuits of the bell and solenoid are in connection with the battery 23.

Upon an outwardly-extended portion 30 of the pointer 16 is a spring-contact 31, designed to engage with either of the binding-posts 20 or 25, and also on this extension is a spring-contact 32 for engaging with the binding-post 26. The core of the solenoid has a link connection Set with a lever 35, to which the stem 36 of a cut-off valve in the watersupply pipe 37 is attached. This valve is designed to be opened as the core 33 is drawn upward and into the solenoid, and to assist in the movement we employ a spring 38, which is connected at one end to the lever and at the other end to some fixed device.

It may be here stated that while we have shown and described a solenoid for opening the valve in the pipe 257 any other electronictive device may be employed; also, the regulating-valve may be arranged in connection with a pump for supplying water to a boiler.

in connection with the alarm 18 we may employ a supplemental alarm consisting of a whistle 89, having connection with the cylinder 5, so that the alarm may be given to the engineer or other attendant should the object be at such a distance that the bell could not be heard. The stem of the whistlevalve is engaged by a finger 40 on a lever 4E1, on which is adjustably arranged a weight 42. From this lever il link l3 extends downward and is pivotally connected to one end of a lever at, pivoted on a lug onthe casing 12., This lever 44 is made in two pivotally-conneeted sections, the section 45 being designed to swing relatively to the main section when the outer end of the lever is moved downward. To hold them rigidly together, however, when the outer end of the lever is moved upward, the adjacent ends of the two sections are oppositely beveled, as indicated at 46.

Secured to the casing 12 is a slotted plate 47, having divergent guide-arms 4C8 at its upper end, and at one side of said plate 4.7 is a latch-block 49, the said latch-block being pivoted to the plate 4-7, and it has a portion 50, designed to extend across the slot in the plate a7 to engage with the end of the lever 44. A rod 51 extends outward from the block 49 and normally rests on supportingplates 52 53, mounted on the shaft 15. One of the said plates, here shown as the plate 52, is rigidly attached to the shaft 15, while the plate 53 is adjustably connected to said plate 52that is, the plate 53 is mounted to swing on the shaft 15, and it is provided with a slot through which a screw passes and engages in a tapped hole in the plate 52. By making the plate in two parts the length of bearing for the rod 51 may be adjusted so that the Whistle may be operated at the desired time.

In the operation should the water in the boiler or other vessel rise above a desired point the float by rising in the cylinder 5 will cause the contact 31 to engage with the hinding-post or contact 19, thus closing the circuit through the bell 18 and causing an alarm. Should the level of the water fall below a desired point, the contact 31 will engage with the binding-post or contact 25, sounding the alarm 18, and by a further movement of the pointer 16 the contact-plate 32 by engaging with the contact or binding-post 26 will close the circuit through the solenoid, which by drawing in the core 33 will open the valve in the pipe 37 to admit water to the boiler. At this time the support for the rod 51 will be rocked sufficiently forward to release said rod, thus permitting the latch-block 49 to be swung upward, releasing the end of the lever -14, so that by means of the weight t2 the valve of the whistle 39 will be opened.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. An alarm device for high and low water, comprising a cylinder, a float in the cylinder, a steam-whistle having connection with the cylinder,-a lever having a part for engaging with the valve-stem of said whistle, a slotted plate, a two-part lever mounted to swing and having connection with the first-named lever, the free end of said two-part lever being designed to pass into the slot of said plate, a pivoted locking-latch for the lever, a holding device for said latch movable to releasing position by the float, an electric alarm, and means operated by the float for controlling the circuit of said electric alarm.

2. In connection with a boiler or other water vessel, a cylinder, a casing extended from said cylinder, a float in the cylinder, a shaft arranged transverselyin the casing and connected to the float, a steam-whistle on the cylinder, a lever having a part for engaging with the valve-stem of the said whistle, a slotted plate on the casing, a two-part lever mounted to swing on the casing and having connection with the first-named lever, the free end of said two-part lever being designed to pass into the slot of said plate, a lockinglatch for the lever, pivoted to said plate, a rod extended outward from said latch, and a supporting device for said rod, attached to the shaft extended through the casing.

3. In combination with a boiler or other wa ter vessel, a cylinder, a float arranged in the cylinder, a casing extended from the cylinder, a shaft extended transversely of the easing, a steam connection between said shaft and the float, an adjustable supporting-plate on the shaft, a whistle in the cylinder, a slotted plate on the casing, divergent guidefingers at the upper. portion of the plate, a weighted lever having a portion for engaging with the valve-stem of the whistle, a lever mounted to swing in the casing and having connection with the weighted lever, the free end of said last-named lever being designed to pass into the slot of the plate, a latch-block pivoted to the plate and having a portion for extending across said slot to engage with the lever, and a rod extended from the latchblock for engaging the supporting-plate.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
